Walk him up the driveway through the door up into your room and see what it is he really wants.
Look at him in the eye listen to him and try to speak and see if he'd do the same.
Watch his heart that he claims is broken and be the judge of whose fault it really is.
Take him to the water look into his eyes as you test his memory- he'll look away every time.
It'll break you're heart, but it was already broken anyway. Because you would've let him in knowing he doesn't know respect he doesn't know silence he doesn't remember you.
You'll suddenly realize that you didn't love him to pieces, you loved him in pieces... while he never even loved you at all.
